Your water at a glance
Soft water. Know your mineral level.
This figure helps you choose appliance settings. Hardness describes dissolved minerals and does not establish whether every water-quality requirement was met.
38 mg/l as CaCO₃
Soft ≤100 · Slightly hard ≤150 · Moderately hard ≤200 · Hard ≤300 · Very hard >300 mg/l. DWI hardness bands; not safety grades.

Drinking-water results
What do the important results mean?
Read the status, sample range and source requirement together. A low average can hide an individual exceedance. Green labels mean the supplier reported no exceedances for that parameter and period; amber calls for source context.
E. coli
Mean at or below the source limit
Published mean
0 number/100ml
Source reference: 0 number/100ml
A microbiological indicator. The reported sample results and any failures matter more than an average bacterial count.

For a new taste, smell, colour or supply problem, check current supplier advice. Annual data is not a live incident feed.
Official supplier help ↗Taste, appearance and mineral content
Chlorine, pH and minerals answer different questions. Calcium and magnesium help describe hardness; chloride is different from treatment chlorine. None is a stand-alone water-quality score.
Free chlorine residual
Disinfectant remaining after treatment. It can influence taste and smell; a lower concentration is not automatically better.
See the measurement and context ↓pH
Describes acidity and alkalinity on a scale, rather than an amount of a substance. Where the source gives a range, both its lower and upper bounds matter.
See the measurement and context ↓Calcium
A naturally occurring mineral that contributes to hardness. Calcium alone is not the same measurement as total hardness.

Every result retains its original units, range, sample count and source notes. Comparisons use the reference printed in this report; qualitative references and missing limits are not converted into invented pass/fail judgements. Unlisted substances are not necessarily absent from the water.
Parameters without their own explanation: A substance monitored in this supplier report. The source reference, units, sample range and any reported failures provide its context; the number alone is not a water-quality rating.
Source note on 48 of these parameters: “Supplier reports 0% of samples failing its requirement. This is a historical percentage, not a current incident or a reconstructed failure count.”

Official supplier report for this supply zone, retrieved with postcode SK14 1AJ. Town pages that cite this zone show their own supplier-confirmed example postcode. This is an example supply area, not a measurement at every address in the towns it serves.
The supplier describes a rolling 12-month window updated weekly. Its update date is not an exact sampling-period end date. Overlapping rolling windows are not annual trend points.
All published numeric parameters are retained, including censored readings and historical failures. These results are not a statement about current incidents.
Supplier reports 0% of samples failing its requirement. This is a historical percentage, not a current incident or a reconstructed failure count.
Hardness: 45 samples · reported range 31 to 52 mg CaCO3/l.
Status labels describe the published parameter and period. Historical exceedances do not automatically establish a current incident. Numerical limits are taken from the original report, not applied indiscriminately across countries, dates or sampling locations. DWI explains how standards work in England and Wales.

Questions about water in Hyde
Is the water in Hyde hard or soft?
Soft. United Utilities’ report for Rolling 12 months; updated 4 September 2026 gives total hardness of 38 mg/l as calcium carbonate for the Haughton Green And Denton supply area. That is the area returned for the example postcode SK14 1AJ; supply can differ by address, so check your full postcode.
Who supplies water in Hyde?
United Utilities supplies the example postcode SK14 1AJ (Haughton Green And Denton supply area). Other addresses may differ: check your full postcode or use United Utilities’ water quality information.
Do I need a water softener in Hyde?
At 38 mg/l as calcium carbonate, in the middle of the soft band (up to 100 mg/l), water leaves little limescale. That is about 2.1 °dH or 2.7 Clark degrees, units many appliance manuals use, so check your dishwasher setting. A softener is not normally needed to reduce scale.
How up to date is the water information for Hyde?
Hardness and water-quality results both come from United Utilities’ rolling summary (12 months, updated 4 September 2026). These are area summaries, not live tests of your tap; see the original United Utilities report.
